The development of selective and sensitive of new molecular sensors for the detection of metal cations represents an attractive area into the supramolecular chemistry. In this sense, we proposed the design and synthesis of fluorescent sensors that have in their structures biphenyl derivatives and can be synthesized from certain natural products such as vanillin or eugenol. Considering that the more rigid structure of a chemosensor tends to generate change fluorescence, silica was used to embed them in order to aim this property. Mesoporous silica such as SBA-15 is a suitable inorganic support due to its uniform wide channels that can immobilize organic chemical sensors. In this work we evaluate the necessary experimental conditions to carry out the embedding of bis-vanillin and bis-eugenol -two potential precursors of chemosensors- in the porous structure of the mesoporous silica SBA-15 through a microwave assisted process. The physicochemical characterization of the developed bis-vanillin-SBA-15 and bis-eugenol-SBA-15 materials confirmed the successful immobilization of these molecules in the mesoporous composite. The most important characteristic of these systems is the possibility of activating the release of the organic molecules embedding into SBA-15, depending on the liquid medium in which these composite are suspended. These findings give an important insight into these hybrid systems in the development of chemical sensors for the detection of metal cations in different medium.
